Safety Instructions

General Power Tool Safety Warnings

WARNING Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/ or serious injury. Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mainsoperated (corded) power tool or battery-operated (cordless) power tool

Work area safety

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

Electrical safety

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

Personal safety

• Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
• Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool
• safety principles. A careless action can cause severe injury within a fraction of a second

Power tool use and care

• Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

Battery tool use and care

• Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
• Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
• Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130°C may cause explosion.
• Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

Service

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
• Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Safety instructions for reciprocating saws

• Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the workpiece by hand or against your body leaves it unstable and may lead to loss of control.
• Keep hands away from the sawing area. Do not reach under the workpiece. Contact with the saw blade can lead to injuries.
• Hold the power tool firmly with both hands and make sure you have a stable footing. The power tool can be more securely guided with both hands.
• Only bring the power tool into contact with the workpiece when switched on. Otherwise there is danger of kickback if the cutting tool jams in the workpiece.
• Ensure that the footplate is always resting on the workpiece while sawing. The saw blade can jam and lead to loss of control over the power tool.
• When the cut is completed, switch off the power tool and then pull the saw blade out of the cut only after it has come to a standstill. In this manner you can avoid kickback and can place down the power tool securely.
• Always wait until the power tool has come to a complete stop before placing it down. The application tool can jam and cause you to lose control of the power tool.
• Use only undamaged saw blades that are in perfect condition. Bent or dull saw blades can break, negatively influence the cut, or lead to kickback.
• Do not brake the saw blade to a stop by applying side pressure after switching off. The saw blade can be damaged, break or cause kickback.
• Ensure that the material is securely clamped. Do not support the workpiece using your hands or feet. Do not touch any objects or the floor with the saw while it is running. There is a risk of kickback.
• Use suitable detectors to determine if there are hidden supply lines or contact the local utility company for assistance. Contact with electric cables can cause fire and electric shock. Damaging gas lines can lead to explosion. Breaking water pipes causes property damage.
• In case of damage and improper use of the battery, vapors may be emitted. The battery can set alight or explode. Ensure the area is well-ventilated and seek medical attention should you experience any adverse effects. The vapours may irritate the respiratory system.
• Do not open the battery. There is a risk of short-circuit-ing.
• The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit may occur, causing the battery to burn, smoke, explode or overheat.
• Only use the battery with products from the manufacturer. This is the only way in which you can protect the battery against dangerous overload.
• Protect the battery against heat, e.g. against continuous intense sunlight, fire, dirt, water and moisture. There is a risk of explosion and short-circuiting.

Noise/vibration information
Noise emission values determined according to EN 62841‑2‑11. Typically, the A-weighted noise level of the power tool is: Sound pressure level 86 dB(A); sound power level 97 dB(A). Uncertainty K = 5 dB. Wear hearing protection Vibration total values ah (triax vector sum) and uncertainty K determined according to EN 62841‑2‑11: Cutting boards with saw blade S 2345 X: ah,B = 18.7 m/s2, K = 1.5 m/s2, Cutting wooden beams with saw blade S 2345 X: ah,WB = 23.1 m/s2, K = 1.5 m/s2. The vibration level and noise emission value given in these instructions have been measured in accordance with a standardised measuring procedure and may be used to compare power tools. They may also be used for a preliminary estimation of vibration and noise emissions. The stated vibration level and noise emission value represent the main applications of the power tool. However, if the power tool is used for other applications, with different application tools or is poorly maintained, the vibration level and noise emission value may differ. This may significantly increase the vibration and noise emissions over the total working period. To estimate vibration and noise emissions accurately, the times when the tool is switched off or when it is running but not actually being used should also be taken into account. This may significantly reduce vibration and noise emissions over the total working period. Implement additional safety measures to protect the operator from the effects of vibration, such as servicing the power tool and application tools, keeping their hands warm, and organising workflows correctly.

Rechargeable battery

Bosch sells some cordless power tools without a rechargeable battery. You can tell whether a rechargeable battery is included with the power tool by looking at the packaging.

Charging the battery

Use only the chargers listed in the technical data. Only these chargers are matched to the lithium-ion battery of your power tool.

Note : Lithium-ion rechargeable batteries are supplied partially charged according to international transport regulations. To ensure full rechargeable battery capacity, fully charge the rechargeable battery before using your tool for the first time.

Inserting the Battery
Push the charged battery into the battery holder until it clicks into place.

Removing the Battery
To remove the rechargeable battery, press the battery release button and pull the battery out. Do not use force to do this.

Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water. Only store the battery within a temperature range of −20 to 50 °C. Do not leave the battery in your car in the summer, for example. Occasionally clean the ventilation slots on the battery using a soft brush that is clean and dry. A significantly reduced operating time after charging indicates that the battery has deteriorated and must be replaced. Follow the instructions on correct disposal.

Assembly

Remove the battery from the power tool before carrying out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be removed for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.

Inserting/changing the saw blade

• When fitting or changing the saw blade, wear protective gloves. Blades are sharp and can become hot when used for prolonged periods of time.
• While replacing the saw blade, ensure that the saw blade receptacle is free of material residue, e.g. wood or metal chips

Selecting the saw blade
Only use saw blades with a 1/2″ universal shank. The saw blade should not be longer than required for the intended cut.

Inserting the saw blade (see figure A)
Firmly push the saw blade (1) into the saw blade receptacle (4) until it audibly engages. The locking sleeve (3) consequently rotates by approx. 90° and locks the saw blade in place. If the saw blade (1) is not locked, rotate the locking sleeve (3) by approx. 90° in the direction of the arrow until it is locked in the open position and a clicking sound is heard. Then push the saw blade into the saw blade receptacle (4) once again. Check that it is seated securely by pulling the saw blade. A loose saw blade can fall out and lead to injuries. For particular jobs, the saw blade (1) can also be flipped 180° (teeth point upwards) and refitted.

Ejecting the saw blade

When ejecting the saw blade, hold the power tool in such a manner that no persons or animals can be injured by the ejected saw blade. Turn the locking sleeve (3) by approx. 90° in the direction of the arrow. The saw blade (1) is ejected

Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one’s health. Touching or breathing-in the dust can cause allergic reactions and/or lead to respiratory infections of the user or bystanders. Certain dust, such as oak or beech dust, is considered carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.

• Provide for good ventilation of the working place.
• It is recommended to wear a P2 filter-class respirator.

Observe the relevant regulations in your country for the materials to be worked. Avoid dust accumulation at the workplace. Dust can easily ignite

Operation

Operating modes

Switching the Pendulum On and Off

The orbital action allows for optimal adaptation of cutting speed, cutting capacity and cutting pattern to the material being machined. If possible, change the pendulum setting before switching on the power tool

• Switch the Pendulum on when working in soft and medium-strength materials (e.g. lightweight materials, insulation materials, softwood, other wood, as well as non-ferrous metals, hardwood and plastic). To do so, move down the pendulum action adjusting lever (9).
• Switch the Pendulum off for clean cut edges as well as for working in thin or hard materials (e.g. sheet metal, steel). To do so, move up the pendulum action adjusting lever (9).

Starting Operation

Switching On and Off

To switch on the power tool, press the lock-off switch to the left (7) first. Then press the on/off switch (8) and keep it pressed. To switch off the power tool, release the on/off switch (8). Then press the lock-off button (7) to the right again

Controlling the stroke rate
You can variably adjust the stroke rate of the power tool when it is on by pressing in the on/off switch (8) to varying extents. Applying light pressure to the on/off switch (8) results in a low stroke rate. Applying increasing pressure to the switch increases the stroke rate. The required stroke rate is dependent on the material and the work conditions and can be determined using practical tests. It is recommended that you reduce the stroke rate when placing the saw blade on the workpiece and when sawing plastic and aluminium. During prolonged periods of use at a low stroke rate, the power tool may heat up significantly. Remove the saw blade and let the power tool run at the maximum stroke rate for around three minutes to cool down.

Working Advice

• Remove the battery from the power tool before carrying out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be removed for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.
• Switch the power tool off immediately if the saw blade becomes blocked

Tips
When sawing lightweight materials, take into account the statutory provisions and recommendations of the material manufacturers.

Before sawing into wood, chipboard, building materials, etc., check for any foreign objects such as nails, screws, etc. and use a suitable saw blade. Switch on the power tool and guide it towards the workpiece you wish to work on. Place the base plate (2) on the surface of the workpiece and saw through the material applying even pressure and feed. Switch the power tool off once you have finished your work. Switch the power tool off immediately if the saw blade jams. Widen the sawing gap slightly with a suitable tool and pull the power tool out.

Swivelling and removable base plate

Thanks to its mobility, the base plate (2) adopts the required angle position of the surface. Depending on the application and the saw blade being used, the base plate (2) can be moved continuously in length direction to different settings. Loosen the screws (13) with the hex key (5) and slide the base plate (2) into the desired position. Re-tighten the screws and check whether the base plate is fixed in place.

Plunge cutting

Plunge cuts may only be applied to soft materials, such as wood, gypsum board, etc. Do not plunge cut metal materials. For plunge cutting, use only short saw blades. Place the power tool so that the edge of the base plate (2) rests on the workpiece, without the saw blade (1) touching the workpiece, and switch it on. When using power tools with stroke rate control, select the maximum stroke rate. Press the power tool firmly against the workpiece and allow the saw blade to plunge slowly into the workpiece. As soon as the base plate (2) rests fully on the workpiece, continue sawing along the required cutting line. For particular jobs, the saw blade (1) can also be fitted after being turned 180° in order to operate the power tool the other way around.

Flush sawing

Protruding components such as water pipes, for example, can be cut directly at the wall using elastic bi-metal saw blades Ensure that the saw blade is always longer than the diameter of the workpiece. There is a risk of kickback. Place the saw blade directly against the wall and bend itslightly by applying lateral pressure to the power tool until the base plate is flush with the wall. Switch on the power tool and saw through the workpiece applying consistent lateral pressure.

Utility hook

Your power tool is equipped with a utility hook (6) for hanging it, e. g., from a ladder. Simply fold out the utility hook to the required position. When the power tool is hung up, take care that the saw blade is protected from accidental contact. This poses a risk of injury. Fold the utility hook (6) in again when you want to begin work with the power tool.

Coolant/lubricant
As the material heats up along the cutting line when cutting metal, you should apply coolant or lubricant.

Maintenance and Service

Maintenance and Cleaning

• Remove the battery from the power tool before carrying out work on the power tool (e.g. maintenance, changing tool, etc.). The battery should also be removed for transport and storage. There is risk of injury from unintentionally pressing the on/off switch.
• To ensure safe and efficient operation, always keep the power tool and the ventilation slots clean.

Carefully clean the saw blade receptacle with a soft cloth. To do so, remove the saw blade from the power tool. Keep the saw blade receptacle operational using suitable lubricants. If the power tool becomes very dirty, this can lead to serious faults. For this reason, do not cut materials which generate large quantities of dust from below or overhead
